Today's nuggets.

Trump swore in Kevin Warsh as Federal Reserve chair at the White House today, ending Jerome Powell's tenure. Warsh was confirmed by the Senate 54–45 last week — the closest Fed confirmation vote in modern history. He takes the helm with US inflation still elevated and oil near $110 a barrel.

Google's annual developer conference opened today in Mountain View. The keynote centred on a major Gemini upgrade — expected to reach the level of OpenAI's GPT-5.5 — plus a new AI agent called Remy that can handle desktop tasks on your behalf. Android XR smart glasses with built-in Gemini were also shown off.

The US 30-year Treasury yield hit its highest level in around a year this week, sitting near 5.13%. Sovereign bond yields are rising globally as oil prices keep inflation (prices rising) elevated — and as investors wait to see how the new Fed chair will respond. Stocks dipped Monday on the pressure.

Nvidia reports quarterly earnings after the bell tomorrow. Analysts expect roughly $78bn in revenue — up around 75% year-on-year — driven by AI data centre chip demand. It's the most-watched earnings call of the year. A miss on guidance could rattle markets that are already jittery from bond yields and the Iran conflict.

Former Health Secretary Wes Streeting confirmed he'll run to replace Starmer when a leadership contest is triggered. Streeting resigned from cabinet on May 14, saying he had "lost confidence" in the PM. 97 Labour MPs have now called on Starmer to go. Streeting needs 81 nominations to formally trigger a contest.
